Nice to hear that you intend to support 256-bit AES encryption. On this issue, I have a specific question relating to embedded images and arbitrary files via addimagefromfile() and embedfile() function. As far as I understand the current library does not encrypt these resources. Only the strictly postscript-based part of the pdf is encrypted. That's what I understood and Ingo nicely confirmed that on the forum. Too bad if the key element of pdf is specifically... the embedded raster bitmap:( In view of what I could read on the adobe site, the most recent encryption scheme allows for more tailored encryption including a very nice 3-values option: Encrypt All Document Contents/Encrypt All Document Contents Except Metadata/Encrypt Only File Attachments I find these options, the third one even more so, very attractive from a specification POV. Allowing for additional smart use for your great library. Do you intend to support any of the above mentionned stuff? Bonne année et bonne santé:) François Hi Rowan,

Do you intend to support any of the above mentionned stuff?
